Abstract

As the loss prevention system using bluetooth has a short communication range, it has a problem which its location is not known if it is strayed out of a certain distance. To overcome shortcoming of such an existing loss prevention system, this paper proposes a GPS-based wireless loss prevention system without communication fee using the LoRa Communication with a long distance. The proposed system performs a remote control application on the smart-phone and then is able to get a long-distance GPS coordinates about the location of the loss prevention system on the google map. For performance evaluation of the implemented proposed system, the experiments for transmitting and receiving data are done in open terrain, indoor and outdoor areas and the experiment results identified the superiority of the proposed system in the long-distance.

블루투스 통신을 이용한 분실 방지기는 짧은 통신거리를 가지기 때문에 일정한 거리를 벗어나면 분실물의 위치를 알 수 없다는 단점을 가지고 있다. 기존 분실 방지기의 단점을 극복하기 위하여 본 논문에서는 상대적으로 긴 통신거리를 가지는 LoRa 통신과 위치 추적을 위한 통신료가 필요 없는 GPS 기반 무선 분실 방지 시스템을 제안한다. 제안하는 분실 방지기는 원격 제어 애플리케이션을 스마트 폰에서 실행하여 Lora 통신을 이용해 분실 방지기의 장거리 GPS 좌표 정보를 구글 지도상에서 확인할 수 있는 시스템이다. 구현된 제안시스템의 성능 평가를 위해 개활지, 실내, 실내-실외에서 데이터 송수신 실험을 진행하였고 실험 결과는 제안된 시스템이 장거리에서도 성능이 우수함을 확인하였다.
